1 Colic is likely to start around age 2 weeks if your infant is full-term (or later if premature). 2  It almost always goes away on its own by 3 or 4 months. 3  Your baby's sex and birth order, and whether you breast- or bottle-feed, donât affect it.  Kids who had colic as babies are no different from those who didnât.
Babies are born with an immature nervous system which fully matures over the first few years of life. For this reason, an immature nervous system has become a theory as to why colic occursâthe nervous system becomes a bit more mature at about three months of age, which coincidentally is when colic usually stops.
